Hi!

I have a weird problem with Python and Digital Assets:
My HDA has a few Python modules which runs every time I press a certain button.
The problem is every time I start a new session I cannot use the button, It gives an error that the python module doesn't exist.
So I have to dive inside the python module, just add a single space to the code and remove it and save the changes to be able to use the tool. I feel it is because the python module does not reload automatically.
I have been dealing with this problem for quite a while and don't know how to solve it.
It would be great if you can help me with this issue.

Thanks

Hello,
If it's just a reload problem just use the “reload(yourModule)” function.
But, as that's the entire module which not found, I suggest you to add your module folder path in your system path :

Hope that help you.

import sys
currentPackagePath = "fullPathToYourScript/moduleFolder"
if not currentPackagePath in sys.path :
    sys.path.append(currentPackagePath)
#Now, import your module should work
import yourModule

Hope that help you.

Thanks Julca
But the python module is a part of my digital asset, How about that?

Isn't possible to add this sort of code once in the onCreated event of the hda ?
Sorry not to be more help. If you can isolate the problem in a simplified hda maybe I can help you better ?

I have the exact same problem, very troublesome. Did you find a solution already?

For anyone stumbling across this topic,
